Price | Class 12 Economics Notes

5.2 APPLICATIONS

This section applies demand-supply analysis to government interventions in markets, focusing on price controls: price ceilings and price floors.

Price ceiling is a government-imposed maximum price, usually set below the equilibrium price to make essential goods affordable. For example, price ceilings on wheat, rice, kerosene, and sugar aim to protect consumers. However, setting a price ceiling below equilibrium creates excess demand (shortage), as quantity demanded exceeds quantity supplied at that price.

In the wheat market example, the equilibrium price and quantity are p and q. Imposing a price ceiling p_c < p* leads to consumers demanding q_c but firms supplying only q_c', causing shortage. To manage distribution, rationing is used where consumers receive coupons limiting purchase quantities, sold through fair price shops. Adverse effects include long queues and black markets where goods sell at higher prices illegally.

Price floor is a government-imposed minimum price, usually set above equilibrium to protect producers or workers. Examples include agricultural price support programs and minimum wage laws. A price floor above equilibrium price causes excess supply, as quantity supplied exceeds quantity demanded.

In the commodity market example, price floor p_f > p* leads to excess supply. To maintain price floor, governments may purchase surplus goods. Price floors can lead to inefficiencies and require government intervention to manage surpluses.

These applications illustrate how government price controls disrupt market equilibrium, causing shortages or surpluses and requiring additional policies to manage outcomes.
